I have begun working on a code (the DALTON quantum chemistry code) that is millions of lines of FORTRAN in size. I would like to debug this through Eclipse so have been working on getting it setup within the IDE.
All is running fine, the code seems to be imported correctly and Eclipse will build it fine (with debug settings) through the makefile that Cmake produces for it. The program will also run fine within Eclipse printing the expected results to the console. However when I come to try debugging it I am presented with a java.lang.NullPointerException error that I am at a loss on how to solve.
Some clue to things not being right can be seen in the project explorer. Eclipse does not seem to handle the "dalton.exe" executable in the same way it handles the executable produced by making (same compiler, gfortran) a simple helloworld program I made to test that Eclipse was debugging Fortran files as expected. It appears to be treating the executable as a text file.
I am unable to post images directly as a new user so I will have to provide a link to a hosted version. (I will loiter and answer any questions I find I can to change this :) )
Any help is greatly appreciated.

EDIT:
I have looked at the .metadata/.log for the workspace, I can't make much of the errors I'm afraid. It logs the following:

EDIT2:
Some progress perhaps:
I am now launching eclipse with sudo. I switched to the Debug window, and to the Executables tab in the console. There I right clicked in the table and imported dalton.x as an executable. It is of note that the source code was found successfully and the executable imported fine.
Running a debug build with this presents a new error: Failed to set program arguments, environment or working directory. Unable to set working directory: "/Users/james/QC_Codes/Dalton/build": No such file or directory. Unable to set working directory: "/Users/james/QC_Codes/Dalton/build": No such file or directory. Unable to set working directory: "/Users/james/QC_Codes/Dalton/build": No such file or directory.
I have double checked. These directories exist and should be accessible.
Again any advice is greatly appreciated.
I experiment onwards...
